Yeah just make a new project in v9 copy the power grades in gallery to regular still store and then save project. Then open 10 and import that project, the names should have stayed and in gallery page you should he able to move those into power grades retaining the names.

I was gonna suggest exporting a DPX still of the Powergrade correction, then import the DPX still (and associated correction) together to the still page and then to the Powergrade section. But open the old session should work, too.

True, the entire stills procedure within Resolve is screwy because it's based on timeline number and scene (if memory serves). I wish they could save stills based on the user-added name. This wreaks havoc when you have multiple timelines and needed to export lots of stills from the same session, all of which technically have the same "Still Name" (like 1.3.11 or something like that).

But you can grab a DPX still of a powergrade and then use that still and the associated DRX correction file, then just rename it. You only have to do it once, assuming you don't have hundreds of powergrades.

Blackmagic should probably re-examine the methodology behind importing stills, corrections, and powergrades and have a mode that will automatically retain the names and put them in the right place. This is doable -- it's more a question of what they prioritize for features and fixes.
